There's no need to store an incoming addba request in struct mlme_ext_info. We only need the addba request to copy some of its fields into our addba response. It's simpler to pass the incoming request's management frame to issue_action_BA as an additional parameter. issue_action_BA can then extract the required fields. If issue_action_BA prepares a request rather than a response, the caller sets the parameter for the incoming request to NULL.
